Driving in **bad weather** can contribute to the **fatigue** of the driver, which increases the risk of accidents. Fatigue can be both **physical** and **psychological**. Physical fatigue generates a feeling of tiredness, while psychological fatigue makes it difficult to concentrate.

- **External factors**, such as the condition of the road, can contribute to fatigue. Adverse conditions, such as heavy rain or fog, require greater attention and effort, which can exhaust the driver more quickly.

- Fatigue manifests with symptoms such as **difficulty concentrating**, **blurred vision**, and **slower reactions**. These symptoms are dangerous when driving, as they affect the ability to make quick and safe decisions.

For these reasons, it is important to **rest more frequently** when driving in bad weather conditions to avoid fatigue and maintain safety on the road.
